Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A pressure measuring and flow-rate controlling device comprising: a flattening plate comprising a fluid cavity in which a fluid layer is established; a flexible contact membrane provided on the flattening plate and in direct contact with the fluid cavity; a support member configured to secure the flattening plate against a sample; a pressure adjuster; an inlet tube configured to intercommunicate with the fluid cavity; and an outlet tube configured to intercommunicate with the fluid cavity, wherein the pressure adjuster is configured to control a flow rate of a fluid passing through the fluid cavity based on cell pressure of the sample.
The device measures pressure and controls fluid flow. It has a flattening plate with a fluid-filled cavity. A flexible membrane on the plate touches the fluid. A support holds the plate against a sample. A pressure adjuster controls fluid flow through the cavity based on the sample's cell pressure. Inlet and outlet tubes connect to the fluid cavity, allowing fluid to enter and exit, and the pressure adjuster dynamically adjusts the flow rate in response to the sample's pressure.
2. The pressure measuring and flow-rate controlling device according to claim 1 , wherein the support member comprises: a spring; and a brace.
The pressure measuring and flow-rate controlling device includes a flattening plate with a fluid cavity, a flexible membrane on the plate touching the fluid cavity, a support to secure the plate against a sample, a pressure adjuster, and inlet/outlet tubes connected to the cavity, where the adjuster controls flow based on sample cell pressure. The support member specifically includes a spring that provides compliance, and a brace that provides structural reinforcement to the support member.
3. The pressure measuring and flow-rate controlling device according to claim 1 , wherein in response to the cell pressure of the sample increasing, the flattening plate and the flexible contact membrane closes the fluid cavity.
The pressure measuring and flow-rate controlling device includes a flattening plate with a fluid cavity, a flexible membrane on the plate touching the fluid cavity, a support to secure the plate against a sample, a pressure adjuster, and inlet/outlet tubes connected to the cavity, where the adjuster controls flow based on sample cell pressure. When the sample's cell pressure increases, the flattening plate and flexible membrane squeeze the fluid cavity, effectively reducing or closing off the fluid flow path.
4. The pressure measuring and flow-rate controlling device according to claim 1 , wherein in response to the cell pressure of the sample decreasing, the flattening plate and the flexible contact membrane opens the fluid cavity.
The pressure measuring and flow-rate controlling device includes a flattening plate with a fluid cavity, a flexible membrane on the plate touching the fluid cavity, a support to secure the plate against a sample, a pressure adjuster, and inlet/outlet tubes connected to the cavity, where the adjuster controls flow based on sample cell pressure. When the sample's cell pressure decreases, the flattening plate and flexible membrane move away from each other, effectively increasing or opening up the fluid cavity and allowing more fluid flow.
5. The pressure measuring and flow-rate controlling device according to claim 1 , wherein the outlet tube further comprises a dripping end.
The pressure measuring and flow-rate controlling device includes a flattening plate with a fluid cavity, a flexible membrane on the plate touching the fluid cavity, a support to secure the plate against a sample, a pressure adjuster, and inlet/outlet tubes connected to the cavity, where the adjuster controls flow based on sample cell pressure. The outlet tube has a "dripping end," designed to allow fluid to exit the device in a controlled, drop-wise manner, potentially for precise dispensing or monitoring purposes.
6. A pressure measuring and flow-rate controlling device comprising: a flattening plate comprising a fluid cavity; a flexible contact membrane provided on the flattening plate and in direct contact with the fluid cavity; a support member configured to secure the flattening plate against a sample; a pressure adjuster; an inlet tube configured to intercommunicate with the fluid cavity; and an outlet tube configured to intercommunicate with the fluid cavity, wherein the pressure adjuster comprises: a pressurization plunger; and a manometer connected to the inlet tube.
The device measures pressure and controls fluid flow. It has a flattening plate with a fluid cavity. A flexible membrane on the plate touches the fluid. A support holds the plate against a sample. Inlet and outlet tubes connect to the fluid cavity. The pressure adjuster includes a pressurization plunger to apply pressure to the fluid, and a manometer to measure the fluid pressure. The pressure adjuster dynamically adjusts the flow rate in response to the sample's pressure by adjusting the plunger.
7. The pressure measuring and flow-rate controlling device according to claim 6 , wherein the support member comprises: a stationary securing frame; a spring; and a pin.
The pressure measuring and flow-rate controlling device includes a flattening plate with a fluid cavity, a flexible membrane on the plate touching the fluid cavity, a support to secure the plate against a sample, a pressure adjuster including a pressurization plunger and a manometer connected to the inlet tube, and inlet/outlet tubes connected to the cavity. The support member has a stationary securing frame, a spring for compliance, and a pin to fix other support member parts in place.
8. The pressure measuring and flow-rate controlling device according to claim 6 , wherein in response to the cell pressure of the sample increasing, the flattening plate and the flexible contact membrane closes the fluid cavity.
The pressure measuring and flow-rate controlling device includes a flattening plate with a fluid cavity, a flexible membrane on the plate touching the fluid cavity, a support to secure the plate against a sample, a pressure adjuster including a pressurization plunger and a manometer connected to the inlet tube, and inlet/outlet tubes connected to the cavity. When the sample's cell pressure increases, the flattening plate and flexible membrane squeeze the fluid cavity, effectively reducing or closing off the fluid flow path.
9. The pressure measuring and flow-rate controlling device according to claim 6 , wherein in response to the cell pressure of the sample decreasing, the flattening plate and the flexible contact membrane opens the fluid cavity.
